Japan could become one of the first countries in the world to end the HIV epidemic, says the president of Gilead Sciences Japan, Kennet Brysting. The idea for now could seem a little too ambitious, but it is not entirely unrealistic, given that the availability of medicines that can prevent transmission of HIV. Drugs are not the cure, but control over the spread of virus to the point where the disease is no longer a major public health threat.
Gilead's have two key drugs, Truvada and lenacapavir. These two are playing a crucial role in prevention. Truvada is taken as a daily pill, while lenacapavir requires two injections per year. It can make the virus undetectable in infected individuals and prevent transmission to those who are not infected yet. In trials, lenacapavir showed 100% efficacy in preventing HIV infections. This is why it is describe as "almost a vaccine".
In 2024, Japan also approved Truvada for HIV prevention, but the country has yet to approve lenacapavir for the same. Until now, people in Japan had been importing generic versions of Truvada or purchasing it from clinics that source it from overseas.
Up until now, Japan reported around 25,000 HIV infections, whereas 669 new cases were reported in 2023. For seven consecutive years, the number of new infections remained under 1,000. The downward trend thus shows that the virus has been controlled, however, getting to zero new infections remains the ultimate goal.
Brysting too acknowledged that simply having effective drug is not enough. What is important is to have a proper implementation, access and healthcare support to make sure that these treatments are widely available and effective.
The biggest challenges is testing rates. There is a need to increase testing rates. At this very moment, around 86% people infective with Japan have been tested, but the goal is to increase it up to 95%, with an ideal goal of 100%. Without widespread testing, many infected people may not even know that they are infected and it could transmit the virus.
Another measure issue is the cost of preventative medication. While Japan's health insurance covers treatments for diseases, it does not cover preventative drugs. Those who purchase Truvada for prevention, pay around $470 per month. Some clinics in Tokyo offer generic alternatives too, which is cheaper, but they are not ideal.
Brysting expressed concern that individuals importing medications might not be consulting doctors regularly, which is essential for monitoring HIV status and overall health. Truvada users need to be tested for HIV initially and every three months, along with screenings for other infections and kidney function checks. Without proper medical supervision, there is a risk of misuse and inadequate protection.
Gilead is in discussions with Japanese authorities to improve access and insurance coverage for Truvada, and progress is being made. Japan has shown efficiency in approving critical medicines, as seen during the COVID-19 pandemic when Gilead’s remdesivir was approved in just three days.
Gilead at this moment is not only focused on HIV and hepatitis C, but also expanding into oncology with innovative treatments like CAR-T cell therapy, which strengthens a patient's immune system to fight cancer.
However, Japan’s strict approval processes can slow down drug availability. Phase 3 clinical trials often need to be conducted within the country, and Japan tends to approve medicines much later than other regions. For instance, Truvada was approved for prevention in Japan 12 years after the U.S. and nearly 20 years after its approval for treatment. inancial factors also play a role. The Japanese government adjusts drug prices annually, often reducing them, which can make long-term investment challenging for pharmaceutical companies.

As per the latest data from the Union Health Ministry, India has crossed the 6,000 mark for total COVID-19 cases. 796 new cases were also reported in more than last 48 hours. As per the Indian SARS-CoV-2 Genomics Consortium (INSACOG), among these cases, 163 are from the newly emerging COVID-19 variant XFG.
As per a June 2025 Lancet Report, the recombinant XFG variant originates from LF.7 and LP.8.1.2 and harbours four key spike mutations including His445Arg, Asn487Asp, Gln493Glu, and Thr572Ile and has achieved rapid global spread following its initial detection in Canada.
The Lancet study also reveals that it is a descendant of the Omicron subvariant of the Coronavirus.
The XFG variant also displays “strong immune evasion,” which allows the virus to survive and spread as it manages to evade the body’s natural defences.
As of now, the new variant has been detected in Maharashtra, Tamil Nadu, Kerala, Gujarat, Andhra Pradesh, Madhya Pradesh, and West Bengal.
Several groups in India face a higher risk during spikes in respiratory infections. These include older adults, people with underlying conditions such as heart disease, lung disorders, diabetes, high blood pressure, or obesity, as well as those with weakened immune systems like cancer patients and transplant recipients. Pregnant women, due to physiological changes, and children under five—particularly those who are unvaccinated—are also more vulnerable.
Health experts recommend that individuals in these categories take extra precautions: wear masks in public places, avoid crowded settings, stay indoors when possible, and maintain regular hand hygiene.
Hospitals have been instructed to follow the updated ABC Guidelines 03, released in June 2023, for managing patients showing symptoms of COVID-19 or influenza. Anyone with signs of ILI (Influenza-Like Illness), ARI (Acute Respiratory Infection), or SARI (Severe Acute Respiratory Infection) must be tested. If a Rapid Antigen Test is negative, an RT-PCR test is mandatory. The health department has also directed that district RT-PCR testing facilities be used to their full capacity.
Though the preventive measures are not new, their importance has been renewed. Respiratory viruses often follow seasonal patterns, bringing repeated waves of infection. People with symptoms—or those at high risk—are strongly advised to avoid crowded, closed, and poorly ventilated spaces such as public transport, offices, malls, and theatres, particularly if not wearing a mask. While rapid testing is easily accessible in cities, limited access in rural areas highlights the need for wider distribution.
On May 28, 2025, the World Health Organization (WHO) reported a global rise in SARS-CoV-2 activity, based on data from its Global Influenza Surveillance and Response System. Since mid-February, test positivity rates have been climbing steadily, reaching 11 per cent—levels last seen in July 2024.
The surge is most noticeable in the Eastern Mediterranean, Southeast Asia, and Western Pacific regions, driven by emerging subvariants such as LF.7, XFG, JN.1, and NB.1.8.1. Among these, NB.1.8.1 has drawn special attention and has been classified by WHO as a Variant Under Monitoring (VUM). By late April, 518 sequences of NB.1.8.1 had been reported from 22 countries, making up 10.7 per cent of global submissions.
While NB.1.8.1 appears to spread more easily, current evidence shows no increase in disease severity. Reported symptoms remain familiar—sore throat, fever with chills, nasal congestion, fatigue, and headache.

Shocking to many, expected for more, the US Health Secretary Robert F Kennedy Jr on Monday removed every member of a scientific committee that advises the Centers for Disease Control and Prevention (CDC) on how to use vaccines. He has also pledged to replace them with his own picks.
This is the Advisory Committee on Immunization Practices (ACIP), from where 17 members have been removed. This step has been criticized by many physicians and public health groups.
It may come as a shock to many, but in all fairness, it was known that Kennedy was among the nation's leading anti-vaccine activists before he became the nation's top health official. While he has revealed that the members will be his own pick, he has not said who would he appoint. However, as per reports, this should convene in two week in Atlanta. It is also important to note that the entire roster of committee members were in fact, Biden appointees.
In an opinion piece published in the Wall Street Journal, Kennedy wrote: “Without removing the current members, the current Trump administration would not have been able to appoint a majority of new members until 2028. A clean sweep s needed to re-establish public confidence in vaccine science."
The reports say that the former panel members received an email on a late Monday afternoon that said that their services had been terminated without any reason. Many of whom had not served a full term.
While his steps are being criticized, they must not be seen as a shock as Kennedy had already taken the unusual step of changing COVID-19 recommendations without first consulting the committee.
As per Kennedy, the committee members had too many conflict of interests. However, as the US News reports, Dr Tom Frieden, who is the president and CEO of Resolve to Save Lives and former director of CDC said that Kennedy's actions were based on false conflict of interest claims and that they set a "dangerous and unprecedented action that makes our families less safe". As this step can significantly reduce vaccine access to many people.
“Make no mistake: Politicizing the ACIP as Secretary Kennedy is doing will undermine public trust under the guise of improving it,” he said in a statement. “We’ll look back at this as a grave mistake that sacrificed decades of scientific rigor, undermined public trust, and opened the door for fringe theories rather than facts.”

In a podcast interview, he said, "There is no vaccine that is safe and effective" and told FOX News that he still believes in the now long-debunked idea that vaccines can cause autism. In another 2021 podcast, he urged people to "resist" CDC guidelines on getting their kids vaccinated. "I see somebody on a hiking trail carrying a little baby and I say to him, better not get them vaccinated," he said.
His non-profit also led an anti-vax campaign sticker and he appeared next on the screen to a sticker that read: "If you are not an anti-vaxxer you are not paying attention," reports AP. He told the FOX News that "autism comes from vaccine". However, vaccination has indeed saved more lives.
After taking the charge of the office, Dr Peter Marks, one of the top US Food and Drug Administration (FDA)'s leaders and scientist in vaccine regulation had also been ousted. Several sources have also reported that his resignation was not voluntary, in fact he was reportedly told to 'resign or get fired'.

The Unites States reported 122 new cases of measles last week, which has brought the national total to 1,168 in 2025. This data is released by the Centers for Disease Control and Prevention (CDC). While the outbreaks in Pennsylvania and Michigan have officially ended, others across North America continue to unfold, including in parts of Texas, New Mexico, and Canada.
Measles is caused by a highly contagious airborne virus that spreads through coughing, sneezing, or even breathing near an infected person. It had been declared eliminated from the U.S. in 2000 thanks to widespread vaccination efforts. However, recent declines in vaccination rates and increased international travel have led to a resurgence. The disease can lead to severe complications such as pneumonia, encephalitis (brain swelling), and death, especially in unvaccinated individuals.
The best defense against measles remains the MMR (measles, mumps, rubella) vaccine, typically administered in two doses during early childhood. Yet, the U.S. has seen a growing number of vaccine exemptions, which health experts say undermine community immunity.
Texas experienced the country’s largest outbreak this year, with 742 cases reported across 35 counties. Most were concentrated in Gaines County, where a close-knit, undervaccinated Mennonite community accounted for more than half of the state’s total cases. Two unvaccinated children — aged six and eight — died in separate incidents earlier this year.
As of this week, fewer than 10 individuals in Texas are estimated to still be infectious. State health officials will now provide updates weekly instead of daily, suggesting the worst of the outbreak may be over.
As per CDC if a state reports three or more related cases, it would be defined as an outbreak:
Canada’s Ontario province has seen the longest outbreak in North America, with 2,009 cases and one death in a baby with congenital measles. Alberta has 761 cases. In Mexico, the state of Chihuahua reported 1,940 cases and four deaths.
Measles symptoms start with high fever, cough, runny nose, and red eyes, followed by a spreading rash. Complications can be severe, especially for young children and immunocompromised individuals. There is no specific antiviral treatment; care typically focuses on symptom management and avoiding further spread.
